Flood exposure is linked to increased risks for hospitalisation for all causes and for 10 specific conditions, with relative risks ranging from 1.11 to 1.61 and persisting for up to 210 days.

An analysis of 300 million hospitalisation records from 747 communities in eight countries and territories showed that floods accounted for as much as 0.27% of all-cause admissions.

In addition to the direct health impacts cau
